The AURA EXS is a precision single stage regulator designed to provide control under sub-atmospheric conditions in addition to low flow positive pressure applications. The proprietary hybrid spring design works in tandem with the EXS’s exclusive oversized dual surface diaphragm, allowing precision pressure control under vacuum and positive pressure from 0 bar to 7 bar. AURA’s encapsulated seat design consolidates the numerous moving internal components of a standard regulator into one single piece, allowing for ease of maintenance and minimizing potential failure points. Protected by a 10-micron 360° filter, the encapsulated seat provides significantly more filtration of impurities than the standard pressed-in disk. The encapsulated seat also filters damaging particles from all inlet ports rather than just the pipeline port.

Each EXS regulator is assembled in a Class 100 clean room as a complete assembly with all gauges, valves, and fittings attached. The complete assembly is 100% helium leak checked and cleaned for oxygen service. Additionally, the EXS undergoes multiple flow and function tests to meet the harsh demands and rugged environment of any application worldwide

The EXS is available with Dursan® LS inert and anti-corrosive technology that provides superior corrosive resistance to exotic metals in highly acidic or caustic applications, making the EXS the engineer’s ideal choice for sub-atmospheric and low flow applications.
